Nobody really provided a way to tell writable disk devices from read-only
devices, but all the suggestions pointed me to a simple solution that
solved my current problem, which was to determine the boot disk at
JumpStart time.
The answer: let JumpStart determine it itself. The boot disk can then be
referred to in the rest of the profile as "rootdisk". This resulted in the
following profiles:
For initial installation,
install_type initial_install
system_type server
boot_device any update
partitioning explicit
filesys rootdisk.s0 free /
filesys rootdisk.s1 2048 swap
filesys rootdisk.s3 128
cluster SUNWCXall
For upgrade,
install_type upgrade
cluster SUNWCXall
My original question:
>>I am trying to programmatically generate a profile for JumpStart
>>installations. The issue, here, is that I cannot predict the disk that
>>will be used for O.S. installation.

>>In 99% of cases, I will be able to use "c0t0d0s0", but there are fringe
>>cases where the actual disk where I put my root partition is on a

>>"c1t0d0s0", while the device on controller 0 is the CD-ROM drive).
>>
>>I know I can determine the list of mountable devices using "iostat -xpn",
>>but how can I detect whether the device is a writable disk, suitable for
>>Solaris installation, or if it isn't (CD-ROM drive or other read-only
>>device)? The "format" command seems to be able to do that.

>>Thanks in advance.
